VENTlLATlNG-SCREEN.

SPECIFICATION forming part of Letters Patent No. 345,692, dated July 20, 1886.

Application filed Deeemherfl, 1885. Seiial No. 184,422. (No model.)

To all whom it may concern:

Be it known that I, GEORGE HAYES, aresident of the city, county, and State of New York, have invented certain new and useful Improvements in Ventilating Screens for Blinds, tVindows, Doors, and other Places, of which the following is a specification.

My improvements are intended more particularly as an attachment for window-blinds, capable ofbeing readily removed therefrom when desired; but they are applicable for insertion into or against any suitable opening, such as door-panels, (the panel being removed to form an opening therefor.) They may also be used in they window-opening, or wherever screened ventilation is suitable and occasional opening for vision isdesirable.

My invention consists in a series (or any desired number) of perforated or otherwise apertured slats hung by means of suitable pivots (formed with the slat or attached thereto) to a frame capable of being readily attached to or within any suitable opening, particularly the stiles of blinds or doors, and removed therefrom whenever desired without injury to any part.

It further consists of moving mechanism, in combination with the portable frame, before mentioned, and the slatted screen therein, whereby the slats may be opened and closed at pleasure and secured in either position. The slats, when closed together, form aslatted screen, the object being to admit of ventilation to the exclusion of mosquitoes, flies, and other insects, and to considerable extent dust, and the effects of storms,wind, rain, hail, snow, 850.; when used in railroad-cars, cinders and smoke. They are applicable to dwellings, stores, factories, churches, theaters, &e.'; also railroad-cars, stages, carriages, and marine vessels. They may be inserted into openings and arranged to be slid up, down, or sidewise out of the way, if desired, and when in the opening the slats may be rocked open to permit of free vision. I

In the accompanying drawings, Figure 1 represents a perspective view of the slatted screen, with its frame secured to a windowblind, the near end in section, the blind being of the ordinary pattern with the common wooden slats, all the slats shown closed. Fig. 2 is a vertical section of the same, the blindslats open and the screenslats closed in position for screened ventilation. Fig. 3isasimilar vertical section, showing all the slats open, permitting of free vision downward. Fig. 4 is a similar vertical section showing all the slats open, permitting of free vision upward andingress of light from above. Fig. 5 is an "inside face elevation of the same blind with slatted screens attached. Fig. 6 is a side elevation of the moving mechanism, giving in section the pivots in connection. Fig. 7 is a face plate, hereinafter described, slotted to enable the sliding bar of the moving mechanism to be locked, as desired.

In the drawings, A represents the frame of the screen. This may be made of any suit able material, preferably metal, and secured to any suitable place by screws, bolts, &c.

B represents the parts of the blindframework, to which the frame of the screen is shown attached.

plied to such a blind, the slats of the screen do not interfere with the free movement of the blind-slats, but, as the drawings, Figs. 3 and 4, show, may be moved so as to cooperate there with in obtaining the result desired; and each set of slats (blind and screen) maybe operated independently at will.

, No change is required in any part of the blind or blind-slats to receive the screen, the rod of the blind-slats being operated from be low through an opening left in the screen frame or by other means.

The ventilating-screen, being portable and complete in itself, may be used in summer only and laid away in winter; and it is readily applied to other places-such as doorpanels, head-lights to doors, window-openin gs,

(where there are no blinds,) ear-windows, openings made for ventilation merely, and any other suitable places. I do not confine myself to size or shape, or any peculiar form offrame or slat, as such may be-made to suit circumstances and place of use. They may also be molded into ornamental shapes. The number of apertures in the slats is also immaterial, so long as they are large enough for air-passages and sufficiently small to serve as a screen for the purpose described.

The moving mechanism is shown in Fig. 6. The pivots of the slats c are attached to cogged brackets 0, engaging with a cogged sliding bar, (I, so that as the bar (I is moved upward ordownward the brackets c are moved, rocking the slats to which they are attached. A knob is shown attached thereto for handling. In Fig. 7 is shown a face-plate screwed or otherwise secured to the frame A, having a vertical slot with three side cuts. The stem of the knob connected to the sliding bar (1 passes through this vertical slot, and a sidewise movement carries it into either of the side cuts desired, locking the sliding bar at theheight required.

By this means the slats may be thrown to the several positions shown in Figs. 1, 2, 3, and 4. The sliding bar maybe placed inside the frame A, or outside, and connected in any suitable 11151111101.

I do not confine myselfstrictly to the method shown for moving the slats, as other means may be used.

\Vhat I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A portable screen consisting of a series of perforated (or otherwise apertured) slats pivoted to a frame and adapted to fill or cover an opening and be readily removable there from, as desired, the slats capable of being rocked open to admit of free vision, substan tially as shown and described.

2. A portable panel consisting of perforated slats pivoted to a flanged frame, each slat touching its neighboring slat, so as to form, when closed, a continuous slatted screen, and the set adapted for opening simultaneously by operative mechanism, essentially as shown and described.

3. A portable frame adapted for attachment to suitable openings, as herein set forth, so as to be readily removable therefrom when desired, containing a set of perforated (or otherwise apcrtured) slats hung therein, so as to form, when closed, a continuous ventilatingscreen, the slats adapted for opening, essentially as shown and described.

4. The portable metailio frame A, contain ing the perforated (or otherwise apertnred) screen-slats a, and suitable moving mechanism for rocking the slats, essentially as shown and described.
